Potentiometric Titrations

About Potentiometric Titrations

Potentiometric titrations can be used for dark samples or titrations in solvents other than water which may not be suitable for color-based methods. In addition, use of other electrode types allows potentiometric titrations beyond acid-base chemistry.

Approaches

Potentiometric titrations can be automated, reducing the technician time (and therefore cost) of a measurement significantly, and allowing more complicated experiments.

Liquid samples can be analyzed directly or with dilution to a specific concentration. If the sample contains particles or suspended solids, a filtration or centrifugation step typically precedes the potentiometry.

Sample Considerations

Prior to a Potentiometric titration, a solid sample needs to be dissolved in a solvent, most commonly water.

To assure that matrix effects are accounted for, it is important to discuss the sample with our scientists prior to the measurements being made.
